Description

Technical Field

[0001] This utility model relates to the field of agricultural modernization technology, and in particular to an image acquisition device for agricultural scenarios. Background Technology

[0002] With the development of agricultural modernization technology, image acquisition has been widely used in agricultural scenarios as a key data acquisition method. This technology has efficient and intuitive data acquisition capabilities, which in turn promotes the development of intelligent agricultural monitoring and management.

[0003] In related technologies, traditional image acquisition devices typically employ fixed installation methods, equipped with a basic dustproof and waterproof casing and a single-angle supplementary lighting device, relying mainly on manual adjustment or simple mechanical structures to achieve limited angle adjustment. However, the above-mentioned devices have the following prominent problems in practical applications:

[0004] Insufficient environmental adaptability; traditional equipment lacks waterproof and dustproof design, making it prone to failure in rain, dust, or high humidity environments, and unable to meet the long-term use needs of complex scenarios such as open farmland and greenhouses.

[0005] The adjustment mechanism is rigid, and most devices only support fixed adjustment in a single horizontal or vertical direction, which cannot adapt to the differentiated collection needs of different crop morphologies.

[0006] Data is limited, and the single-camera architecture restricts the ability to acquire multiple views simultaneously. Utility Model Content

[0007] In response to the shortcomings of the existing production technologies, the applicant provides an image acquisition device for agricultural scenarios, which is adaptable to different working heights and widths, has multi-angle adjustment functions to meet the needs of different plant morphologies, and has good waterproof and dustproof effects.

[0009] An image acquisition device for agricultural scenarios includes:

[0010] The adjustment bracket module is mounted on the environmental carrier and is used for adjusting the position of the camera module;

[0011] The controller module is fixed on the mounting base of the adjustment bracket module;

[0012] The camera module has a camera movement adjustment plate with at least one adjustment slot. The camera movement adjustment plate is mounted on the mounting base by cooperating with the adjustment slot and being assembled by the eleventh connecting bolt.

[0013] The fill light module is mounted on the top of the camera module via a fill light universal adjuster, which drives the fill light to rotate and adjust at multiple angles.
